Tony Fadell's Nest, the smart thermostat, officially started selling in the UK.

Nest, who was recently acquired by Google and founded by the ipod's father, Tony Fadell, announced today that its smart thermostat was officially launched in the UK for a price of £ 179 (249 pounds with installation service).

Google has lost 3.2 billion of billions of dollars in its takeover of Nest, though many people are puzzled by the deal, but for Google, which is interested in integrating global information, nest can help penetrate the home and bring more information worth the price. For Nest, Google can help it quickly expand its global market. The UK is the third stop for Nest overseas expansion (the United States and Canada are the first to second). But Nest's products are actually installed in more than 120 countries around the world.

But this first station still spent nest a year of preparation time. Because of the difference between the British and American heating systems, and the 100-home test takes time, it will not be available in the UK until 1 years after the product was listed in the United States in 2012.

The thermostat is called an intelligent thermostat because it can basically adjust the temperature according to the user's preferences after installation. But Tony does not like to call it "intelligence" because the word "smart" is already rotten on the street. In fact, he preferred to call the nest thermostat a "learning type" thermostat. Thermostat learning time is about a week, because this is basically the user's most typical life cycle. By observing the user's regulation, the thermostat can understand the temperature that the user likes at different times and adjust accordingly. Sensors can sense whether no one is at home and automatically stops powering.

In addition, users can manually control thermostat, or through the smartphone app or web platform for remote control and can review the history of the heating supply. On the energy-saving nest and game reward mechanism, each time the temperature is lower than the normal temperature of the behavior can receive a green leaf.

Nest wants its thermostat to replace the traditional thermostat, because it can automatically learn the customer's favorite temperature at different times and adjust accordingly, the Nest thermostat is said to be able to save 20% of its customers ' heating costs each year (British households spend about 1300 pounds a year on heating, So the money saved is 260 pounds, that is to say, buy nest 1 years to return to Ben.
